Abstract

1,266,630. Amplifier systems. MARCONI CO. Ltd. 16 Sept., 1970 [19 Dec., 1969], No. 62152/69. Heading H4R. In an arrangement for connecting a number of amplifiers 1, 2, 3, 4, in parallel, the inputs to the amplifiers are connected each to the outputs of a series arrangement of hybrid circuits 6, 7, 8, another output of each of which, except the last, feeds the succeeding hybrid. The outputs of the amplifiers are connected to one input of a second series of hybrids 17, 18, 19, the other input of each of which, except the first, is connected to the output of the preceding hybrid, the output of the last hybrid being the system output. For a large number of amplifiers they may be arranged in two sets each as in Fig. 1 connected in parallel by hybrids (27, 28) Fig. 2 (not shown). The hybrids may be of the asymmetrical type which are adjusted to provide minimum noise level.
